Switch CLI validation commands

This section provides a list of the most common commands and their output for the examples used in this guide.

General commands

show version

Leaf and spine switches must be running a supported version of SmartFabric OS10. Run the show version command to check the operating system version. SmartFabric OS10 is available on Dell Digital Locker (account required).

OS10# show version
Dell EMC Networking OS10 Enterprise
Copyright (c) 1999-2020 by Dell Inc. All Rights Reserved.
OS Version: 10.5.2.2
Build Version: 10.5.2.2

Note: See the SmartFabric OS10 release notes for upgrade instructions.

show license status

Run the command show license status to verify license installation. The License Type: field should indicate PERPETUAL. If an evaluation license is installed, licenses purchased from Dell are available for download on Dell Digital Locker. Installation instructions are provided in the Dell EMC SmartFabric OS10 User Guide on Dell EMC Networking OS10 Info Hub.

show interface status

The show interface status | grep up command is used to verify required interfaces are up, and links are established at their appropriate speeds. In this example, ports 1/1/1-1/1/3 are VxRail nodes, port 1/1/9:1 is a jump host, ports 1/1/49-1/1/52 are the VLTi, ports 1/1/53-1/1/54 are uplinks to the external network, and ports 1/1/55-1/1/56 are uplinks to the spines.

show port-channel summary

The show port-channel summary command is used to view port channel numbers, interfaces used, and status. Port channel 1 (number may vary) is the L2 uplink. Port channels 96 through 97 (numbers may vary) are automatically created spine uplinks. The VLTi is automatically configured as a static LAG using port channel 1000. Ports 1/1/53 and 1/1/54 are port channel members, and (P) indicates each is up and active.

show virtual network

The show virtual network command is used to view virtual networks, VLANs, and interfaces assigned to each VLAN. Port channel 1 (number may vary) is the L2 uplink if configured. Port channel 1000 is the VLTi. Interfaces 1/1/1-1/1/3 are connected to VxRail nodes. Interface 1/1/9:1, shown under VLAN 1811, is the jump host port.

Note: The jump host port was automatically moved from VLAN 4091 to VLAN 1811 during VxRail deployment.

show lldp neighbors

The show lldp neighbors command is useful for identifying connected equipment. Interfaces 1/1/1-3 are connected to the VxRail nodes, and Interface 1/1/9:1 is connected to the jump host. Interfaces 1/1/53-54 are connected to the external network, and 1/1/55-56 are connected to the spines. Mgmt1/1/1 is connected to the OOB management switch.

Note: If an entry is not shown for the jump host, port 1/1/9:1 in the above example, the jump host may be connected to the other leaf switch, or the NIC on the jump host does not have LLDP enabled. This is not required and may be ignored.

show ip interface brief

Run the show ip interface brief command to verify connected interfaces are up, and IP addresses are configured correctly.

In the output below, interfaces 1/1/1-1/1/3 are connected to the VxRail nodes, 1/1/49-1/1/52 are the VLTi, and 1/1/53-1/1/54 are L3 uplinks to the external switches. VLAN 4090, Loopback 1, and Loopback 2 are automatically configured by SFS. VLAN 4090 is used for iBGP, Loopback 1 is the router ID, and Loopback 2 is the VTEP IP address.

Note: Unused interfaces have been removed from the output for brevity.

show ip route

With L3 uplinks, the show ip route command is used to ensure the leaf switches have routes to the external network, 172.19.11.0/24 in this example, to reach the DNS server. This BGP-discovered route is shown in the output below.

VLT commands

show vlt domain_id

This command is used to validate the VLT configuration status. In SmartFabric mode, the VLT domain ID is 255. The Role for one switch in the VLT pair is primary , and its peer switch (not shown) is assigned the Secondary role. The VLTi Link Status and VLT Peer Status must both be up.
